Abstract: Wellbore synthesis techniques are disclosed suitable for use in geothermal applications. Embodiments are provided where open hole drilled wellbores are sealed while drilling in sequenced operations with utilization of phase change materials to form an impervious layer at the wellbore/formation interface in high temperature applications. The techniques may be chemical, thermal, mechanical, biological and are fully intended to irreversibly damage the formation in terms of the permeability thereof. With the permeability negated, the wellbore may be used to create a closed loop surface to surface geothermal well operable in the absence of well casing for heat transfer surfaces for maximizing thermal transfer to a circulating working fluid. Formulations for the working and drilling fluids are disclosed.

Abstract: Operational protocol sequences for recovering energy from a thermally productive formation are disclosed. Sealing, drilling, multiranging, power production and distribution techniques in predetermined sequences for well formation are utilized to recover energy regardless of thermal gradient variation, formation depth and permeability and other anomalies or impedances.

Abstract: A shooting rest, components thereof, and associated methods. The shooting rest includes a frame, a forward firearm support connected to the frame, and a rear firearm support connected to the frame. The rear firearm support includes a stop configured to limit rearward movement of the firearm with respect to the frame when the firearm is fired. A liquid tank is supported by the frame and is configured to hold liquid to increase the effective mass of the shooting rest to reduce recoil felt by a shooter when the firearm is fired.

Abstract: A knife comprising a handle and a blade assembly. The blade assembly includes a blade, a tang, and blade assembly connection structure. The handle includes a receiver configured to receive the tang, and includes handle connection structure. The blade assembly connection structure and handle connection structure are arranged to releasably lock the blade assembly in an installed position on the handle with the tang in the tang receiver.

Abstract: Weapon accessory mount assembly, components thereof, and associated methods. A weapon accessory mount assembly mounts on first and second rails having respective first and second slots of different sizes. The assembly includes an accessory mount for attaching to an accessory and a rail mount for attaching to the first and second rails. The assembly also includes a rail slot key having a first key portion to be inserted into the first slot and a second key portion to be inserted into the second slot to inhibit longitudinal movement of the assembly along the respective first and second rails when mounted thereon.

Abstract: A post driver and remover for the installation and removal of posts includes a post receiver having a post receiver body having a driving end and an opposite driven end. The post receiver body defines a post receiving space having an open end adjacent the driven end and a closed end adjacent the driving end. The post receiving space is sized and shaped to receive an upper end portion of one of the posts. The post receiver body also has a first extractor and a second extractor. The first extractor receives a first post of a first cross-sectional size or shape, and the second extractor has a different size or shape from the first extractor to receive a second post of a second cross-sectional size or shape.

Abstract: Packaging for an optical sighting device and associated components and methods. The optical sighting device has a sighting axis along which a user looks to use the optical sighting device.
